#Mirroring

9

Mirroring is an InterSystems technology for High Availability, Disaster Recovery and Database Backup and OLAP solutions.

Documentation.

Basically the title, I couldn't find anything concrete in the documentation regarding this. The documentation states 'The user-defined ^ZMIRROR routine allows you to implement your own custom, configuration-specific logic and mechanisms for specific mirroring events, such as a failover member becoming primary.' I didn't see any more details on what exactly those mirroring events are besides a failover member becoming primary, which I wasn't sure if that included a DR async becoming primary.

Dear experts,
Please, could you give me any tips about it?

I have two servers (primary and secundary, both are mirroring members) configurated:

primary: SOROSERVER1/HSFOUNDATION2014
secundary: SOROSERVER2/HSFOUNDATION2014

I turned off server "SOROSERVER1" and tried failover to server "SOROSERVER2", but is returning a lot of errors in log (cconsole).
Below are messages saved in cconsole log.

Hello Everyone,

We currently have CSP application that runs under 2 servers(usually primary), and every month the server reboots for patching SERVER1(primary) in the morning and SERVER2(backup) at night.

Whenever the SERVER1 reboots SERVER2 behaves as primary and when SERVER1 comes back up it will act as backup server.

First Patching:

So, when SERVER1 is down, I need to start httpd service for SERVER2 and stop httpd service for SERVER1 (which is now backup server).
